Protect Your Family's Health
Comprehensive Air Quality Services for Your Home
Did you know the air inside your home can be significantly more polluted than the air outside? Everyday contaminants like dust, pollen, pet dander, mold spores, and viruses can get trapped indoors, circulating through your HVAC system and impacting your family’s health and comfort. These pollutants can trigger allergies, aggravate asthma, and contribute to a variety of respiratory issues.
At AA Service Co., we believe your home should be a sanctuary of clean, healthy air. Since 1967, we have provided homeowners in communities like Northbrook and Lake Forest with effective indoor air quality (IAQ) solutions. We offer a complete range of services and products designed to purify your air, control humidity, and create a healthier living environment for you and your loved ones.

Common Questions
Frequently Asked Questions About IAQ
We understand you may have questions about improving your home’s air quality. We’ve compiled answers to some of the most common inquiries we receive from our customers. If you don’t see your question here, please don’t hesitate to reach out to our knowledgeable team.
What are the signs of poor indoor air quality?
Common signs include unusually high dust levels, musty or lingering odors, condensation on windows, and family members experiencing persistent allergies, sinus congestion, or respiratory irritation while at home.
How often should I change my HVAC air filter?
For standard 1-inch filters, we recommend changing them every 1-3 months. If you have pets, smokers, or severe allergies, you should check it monthly. Higher-efficiency media filters can last from 6 to 12 months.
Can an air purifier help with my allergies and asthma?
A high-quality whole-home air purifier can make a significant difference. By capturing airborne irritants like pollen, pet dander, dust mites, and mold spores, these systems can dramatically reduce the triggers for allergy and asthma symptoms.
What is the ideal humidity level for a home?
For optimal comfort and health, the ideal indoor humidity level is typically between 30% and 50%. A whole-home humidifier or dehumidifier helps maintain this balance year-round, protecting you from dry winter air and damp summer conditions.
Is a portable air cleaner enough for my whole house?
While portable units can be effective for a single room, they are not powerful enough to clean the air in an entire house. A whole-home system is integrated with your HVAC unit to purify the air in every room that is heated or cooled.
